Stained glass window in bathroom. I like this vs a normal widow since we seem to always keep the curtains and blinds shut in there anyways. At least this way some good light can still gets into the room. (I totally agree...plus it's so beautiful)
Built-In Drawers between wall studs. We did this with our bathroom vanity. The doors to the vanity consist of mirrors mounted on plywood. It's a great space-saver, and the mirrors make the small space seem much bigger.
